Children play in a water fountain in Bradford, Yorkshire, as Britain is set to bask in its hottest day of the year this weekend, with the fine weather continuing into next week.

- Shut windows and pull down the shades when it is hotter outside. You can open the windows for ventilation when it is cooler.

- Avoid the heat: stay out of the sun and don't go out between 11am and 3pm (the hottest part of the day) if you're vulnerable to the effects of heat.

- Keep rooms cool by using shades or reflective material outside the windows. If this isn't possible, use light-coloured curtains and keep them closed (metallic blinds and dark curtains can make the room hotter).

- Have cool baths or showers, and splash yourself with cool water.

- Drink cold drinks regularly, such as water and diluted fruit juice. Avoid excess alcohol, caffeine (tea, coffee and cola) or drinks high in sugar.

- Listen to alerts on the radio, TV and social media about keeping cool.

- Plan ahead to make sure you have enough supplies, such as food, water and any medications you need.

- Identify the coolest room in the house so you know where to go to keep cool.

- Wear loose, cool clothing, and a hat and sunglasses if you go outdoors.

- Check up on friends, relatives and neighbours who may be less able to look after themselves.
